CLARKSON A. DISBROW, 033 NEW ROCHELLE, NEW YORK, ASSIG-NOR TO THE BAIL JOINT COMPANY, 01'! NEW YORK, N. Y.,

rnnnrcarnn Application filed June 3,

To all whom 2'25 may concern Be it known that I, CLARKSON A. Drsenow,

a citizen of the United. States, residing at w New Rochelle, in the county of VVestchester and State of New York, have invented certain new and useful Improvements in Fabricated Rail Joints, of which the following is a specification.

This invention relates to rail joint construction, and more particularly to novel means for fabricating a rail joint to meet any specified requirements for strength and fishing.

.To that end the invention contemplates utilizing economical and readily obtainable pieces of metal and shapes in connection with the now highly developed modern processes of welding to buildup or fabricate arail joint bar. By this means it is possible to so distribute the metal, adding same in locations where needed and eliminating at some other places where not required so that a joint bar can be made having sufiicient strength in the proper places, while at the same time the weight of the bar maybe reduced, thereby reducing costs, and at the same time providing substantial flexibility in the bar to allow the. rail wave motion to readily pass through the joint without subjecting any part thereof to excessive bending or shearing strains.

A further object of the invention is to provide a fabricated rail joint permitting one rolled section to answer as the primary or foundation bar for several bar sections, thus effecting economy in the cost of rolls and in the handling of same. Y

With these and other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

The present invention lends itself to various modifications without departing from the. spirit or scope thereof, but for illustrative purposes a few preferred and practical embodiments are shown in the accompanying drawings in which- Figure 1 is a perspective view'illustr'ating one embodiment of fabricated rail joint containing the present invention.

RAIL JOINT.

1922. Serial No. 565,550.

Figure l is a vertical central transverse sectional view ofthe 3 on the line H. I

Figures 5, 6 and 7 are a series of detail joint shown in Figure views illustrating the fabrication of a joint l of the Lba-r type.

Like reference numerals designate corresponding parts in the several figures of the drawings.

In fabricating a rail joint, according to the present invention, the primary feature is the use'of what may be termed a primary or foundation bar, which. constitutes the foundation or base upon which is built up the metal parts or pieces to-produce the desired strength and to make the required fishmg, as well as to provide well defined and well located bearing surfaces between the completed'bar and the rail bearing surfaces.

Accordingly, the present invention includes as its base or foundation what may be termed a primary bar designated by the numeral 1. This primary bar may consist of a rolled bar of a light section, ordinarily too light in itself for use as a splicing or rail joint bar. Also this primary bar is usually and preferably of less fishing height than that ofthe rails so that one roll sec tion of primary bar can be made available for fabricating rail joints for different sections of rails, thus effecting economy in the costof rolls and the handling of the same.

Taking for example the form illustrated in Figure l of the. drawings, the primary bar 1 is shown of a channel formation, the lower flange 2 of which may lit the upper side of the flanges of the rails, but being of less fishing height than that of the rails; the upper outturned flange 3 of the said primary bar is disposed below and out of contact with the undersides of the rail heads.

To provide such a bar with properly arranged bearings for engagement with the rail'head, it is proposed according to the present invention to build up thereon in superimposed relation one or more cover plates designatedby the number 4. Also at each location where these cover plates are placed, the same may begraduated in size,

if it be desired to graduate the strength of the built up part of the bar, and it may be found preferable and desirable in some cases to preserve the arrangement of cover plates 1, as shown in Figure 1 of the drawings. That is to say, with the same located respectively at the center and ends of the joint bar, thus leaving the intermediate parts of the bar between the cover plates free to fieX under the influence of the rail wave motion, permitting the latter to more freely pass through the joint without imposing excessive bending or shearing strains In the practical carrying out of the invention it is preferable to fasten the cover plates 4 to the primary bar 1 and to each other by the cry-acetylene or other modern methods of welding, which are now effective for permanently uniting metal parts to each other to make a solid and stable structure.

In addition to the cover plates, a primary bar 1 of the channel design, such as shown in Figure 1 of the drawings, may be additionally reinforced and stiffened by the use of stiffening plates 6 fitting in the channel of the bar 1 at the outer side thereof and welded to the flanges thereof as at 7. These stiffening plates may be of any desired extent and may be arranged in spaced relation, as shown, the same being provided with bolt holes 8 therein to receive the joint bolts, thereby serving the additional function of supporting members for the joint bolts to enable them better to resist bending strains.

In the form of the invention shown in Figure 3 of the drawings, the versatility of the improvement is shown, said View illustrating the cover plates 4t graduated in such a manner as to provide relatively small bearings 9 for the joint bar at the ends of the joint and the placing of relatively small central bearings 10 adjacent to but not spanning the joint between the meeting ends of the rail. This construction may be found desirable in the particular of freeing the bottom corners of the adjacent rail ends from a bearing support. Also in the modified form of construction shown in Figure 3 of the drawings the stiffening members or plates 6 may be formed with inwardly extending reinforcing projections 11 at their top and bottom edges which snugly fit the inner sides of the flanges 2 and 3 of the primary bar 1, producing a stronger construction if that should be specified or desired.

Further, in the group of Figures 5, 6 and 7 of the drawings, there are shown means for making or fabricating a rail joint of L bar construction. Using the desirable metal distribution of an I-beam for the primary bar 1, it is only necessary to build up on the head of said primary bar a bearing member M consisting of one or more cover plates 4 welded to each other and to the bar; also at the bottom of the primary bar may be Welded one or more bearing members or cover plates 12. If it is found necessary, additional strength in the desired location may be given to the primary bar 1 by fitting in the channels at the outer and inner sides thereof the upright strengthening plates 13 welded as at 14 to the flanges of the primary bar.

From the foregoing it is thought that the meets and bounds of the invention will now be apparent without further description, but it is to be understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

I claim:
